To all lwhom t mag/ convenu Be it known that I, IRA VINCENT COLE, a i citizen of the United States, and resident of Seattle, county of King, State of Washington, have invented an Improvement inArrows, of which, the followingdescription, in l connection with the accompanying drawing, is a specification, like characters on the y drawing representing like parts. l0 This invention relates to arrows and has for its general object to provide an improved arrow which will fly more accurately than arrows as now commonly made. It is the universal practice to make each arrow with a nock at `its heel end to receive the string of the bow when the arrow ,is being shot, these nocks being in the nature of saw kerfs or grooves of fixed dimensions which are cut transversely across the end of the arrow. The bow strings which are used vary a good deal in size, some bow strings being relatively small and thin and other bow strings having a considerably largerf diameter. It is an advantage .in shooting an arrow to have the bow string of a size to lit the nock for if the ybow string is smaller than the nock there is an opportunity for more or less lateral movement of the arrow when the latterl is nocked, a fact which is 3 apt to interfere with the accuracy of the shot when the arrowis loosed. On the other l hand, if the string. is larger than the nock then' in nocking the arrow it is necessary to crowd the string into the nock andY under these conditions the friction between the string and the walls of the nock will place a dragon thearrow when it is loosed thus causing it to fall short.

It is 'one of the objects of my present invention to provide an arrow with a novel nock which is adjustable so that it will fit strings of different sizes and can be shot with the same effect from a large string as from a small string. 5 q Another object of my invention is to provide an improved footing for an arrow which is rugged and will withstand hard usage without breakin and which also gives the arrow the desirable balance. In order to give an understanding of my invention I have illustrated in the drawin a selected embodiment thereof which will now described after E'Which the novel features will be pointed out in the appended claims.

1 indicates the shaft or body of the arrow which may be made of any desirable wood. and -which is provided at one end with the usual feathers 3.

4f` indicates the groove or nock in the heel end of the arrow in which the bow string is received when the arrow is being shot. As stated above one of the objects of mypresent invention is to provide an adjustable nock which will automatically 'accommodate itself to different sizes of strings.

In the lconstruction herein shown the portion of the end of the arrow forming one wall of the nock -is movable toward and from the opposite wall of the nock so as to permit the nock to be varied in width.

The shaft 1 of the arrow is usually made of wood, reed or some similar material and I prefer to make the nock 4 in a nock member 5-of metal which is applied to the end ofthe shaft 1. This member 5 is shown as having an axial recess 6 into which the end 7 of the shaft 1 and said nock member may be secured to the shaft in any suitable way, as for instance by means of rivets 8.

The nock member 5 is formed with the 100 `fixed jaw 9 forming one wall of the nock and the movab1ejawl 10 forming the opposite wallof the nock. Said movable jaw is formed with a fin or extension 11 which is received in a slot 12 formed in the 'nock '.105 member 5 and which is pivotally mountedon' the pivot pin `13 that extends transversely through t e nock member. This n 'is formed at its end with a tail 14 which oveilies andis engaged by a spring 1,5k that occuf pies the inner end of the recess or groove 12.

The spring acts normally to throw the taily 14 outwardly and thus move the jaw 10 toward the fixed jaw 9. This spring-impelled movement is limited by the engagement of the face 16 of the fin 11 with the bottom of the groove 12. The pivoting of the jayv 10 and the action of the'spring 15 allows the jaw 10 to swing away from the jaw 9 thus providing a wider nock 4.

' The parts will be so adjusted that when the jaw 10 is at the inward limit of its movement the nock will be rather narrower than the average nock of an arrow and will be of a width to fit the smallest string which would be used. Such a string is indicated at 17 in Fig. 2. If the arrow is :used with a heavieror thicker string, such as indicated at 18 in Fig.- 3, then when the 'arrow is necked the jaw 10 will automatically open away fromthe jaw 9 to receive the string and the arrowv will be held in the nock simplyby the-pressure of the spring 15. The' pressure of the walls of the nock against .the string-therefore, is 'substantially the samewhether the string is--a small stringor a Alarge string and, therefore, .when'the arrow isloosed there is no greater drag-imeposed on the arrow bythe friction of the string against the sides of the nock when it is shot' with a bow using a large string than when it isjshot with a bow using a small string.,

The spring 15 will` preferably be a relatively light spring so that the gripping actionof the jaws on the bow string willbe only sufficient to hold the arrow on the string and will not subject the arrow to any undesirable dragging action when it leaves the string. This automatically-adjustable nock is, therefore, conducive to accurate shooting as the arrow is `subjected to the same action whenloosed regardless of the size of the string. f

In order that. an arrow may fly it is desirable that it should be so balanced that the center of its .weightAswill-be at a point nearer the foot than the heel of the arrow. This fact is frequently secured-by providing the arrow with a footing of hard Wood which is heavier than that from which the body of the shaft is made. While a footingl of-this nature answers the purpose so far as getting the desired balance is conf -cerned yet it has the disadvantage'that hard wood is apt to be brittle-and an arrow thus made is prone to break if it strikes a rock,

target' stand or other hard substance. I

have provided herein an improved footing fony an arrow which not only gives th'eldesired balance but which also is practically indestructible.

AMy improved footing comprises a tubular metal shell'19 which is inserted over the anterior end of the shaft and is provided was without the use of so much metal. lployment of the tubing 19 with the relatively long wings 22, however, adds a very properly used for this purpose. The solid or pointed end may be provided for by inserting a plug 20 into the end of the tubing. The tubing herein shown is provided with diametrically opposite V-shaped slits 21 which extend from the inner toward the outer end of the tubing and which form the two wings 22. This footing may be secured to the arrow by means of rivets 23 extending through the wings. With'this construction the rivets 23 when properly inserted draw the wings 22 tightly against the shaft 1 so as to provide a close fit between the shaft and the wings regardless of any variation in the size of the shaft.`

I will preferably so shape the portions 211 of the shaft which the wings overlie that they fit the interior of the wings so that the. arrow will have a circular crosssection :through the foot portion and the wings willcome flush with the surface of the shaft so as to' make a smooth exterior surface.

If desired, I may make the shaft of the arrow with the tapered insert 25 of a hard wood heavier than that from which the body lof the shaft is made thereby to give the required weight to the foot end of thielirrow e emdesirable element of strength to th'e arrow and prevents theliability of the fo/ot becoming broken upon striking a solid object.

Whilev lI have illustrated herein a selected embodiment of my invention Ido not wish to ibe'limited to -the constructional lfeatures shown.
